Server and method for storing cryptocurrency in cryptocurrency exchange

The present invention relates to a server and a method for storing a cryptocurrency in a cryptocurrency exchange.

Recently, cryptocurrencies such as Bitcoin, Ethereum, and lite coin have become commonplace, and many user terminals are accessing and trading cryptocurrency exchange servers.

The cryptocurrency user terminal receives the cryptocurrency from the cryptocurrency network as a deposit wallet for the user terminal, and then moves the cryptocurrency to the exchange wallet such as a hot wallet of the cryptocurrency exchange server of the cryptocurrency exchange. That is, the exchange wallet of each user terminal on the cryptocurrency exchange server is used only for placing all the cryptocurrencies.

For this reason, when a specific user terminal moves the cryptocurrency to another wallet outside the cryptocurrency exchange, the cryptocurrency is withdrawn from the exchange wallet of the cryptocurrency exchange server. On the other hand, many transactions that occur between users through the cryptocurrency exchange server does not actually occur in the cryptocurrency network, but transactions are processed only in the cryptocurrency exchange server and are recorded and managed in its own DB.

In the meantime, a distributed application (dApp) platform that can issue tokens such as Ethereum and EOS is in the process of airdrops that freely distribute cryptocurrencies to user terminals.

Conventional cryptocurrency exchange server does not provide a personal wallet for receiving the airdrop on the cryptocurrency to the user terminal. As a result, in order for the user terminal to receive the airdrop of the cryptocurrency, the conventional cryptocurrency exchange server must perform a snapshot which stores the balance of the exchange wallets of all the user terminals at the time of receiving the airdrop. However, a number of issues are causing the cryptocurrency exchange server to be unable to provide snapshots of all airdrops.

Referring to FIG. 1, an existing cryptocurrency exchange server provides a

deposit wallet

11 and 12 to a user terminal 13, and processes the cryptocurrency as a

deposit wallet

11 and 12. That is, the user terminal 1 (13) can receive the Ether (ETH) to the Ethereum deposit wallet 11 of the user terminal 1 (13) through the cryptocurrency exchange server, the BTC to the wallet 12 for deposit You can deposit bitcoin. The deposit wallet referred to herein may be a collective term for the addresses of

cryptocurrency wallets

11 and 12 of a user terminal capable of receiving or withdrawing a specific cryptocurrency.

Referring to FIG. 2, the existing _{cryptocurrency} exchange server receives the deposit (t _i21 ) of the _{cryptocurrency} from the external wallet 21 into the deposit wallet 22e of the user terminal, and then receives the received _{cryptocurrency} after a predetermined time. The transfer wallet 22e moves to the exchange wallet 25 (t _i22 ). The cryptocurrency exchange server transfers the cryptocurrency deposited in the user's wallet (22a, 22b, 22c, 22d, 22e) to the exchange wallet 25 immediately or within about 2 hours after depositing it for storage, for convenience of withdrawal. do. As a result, when the user terminal requests withdrawal of the cryptocurrency from the cryptocurrency exchange server, the cryptocurrency exchange server withdraws the cryptocurrency from the exchange wallet 25 instead of the

wallets

22a, 22b, 22c, 22d and 22e. t _o21 ). Here, the cryptocurrency exchange server receives the deposit of the cryptocurrency means that the transaction occurs in the cryptocurrency network and the corresponding cryptocurrency is deposited in the

wallets

22a, 22b, 22c, 22d and 22e.

Transactions occurring between the user terminals in the cryptocurrency exchange server are stored in the DB unit 2b. Transactions occurring between the user terminals are not recorded in the blockchain because the transaction does not occur in the actual cryptocurrency network. . In this case, the DB unit 2b reflects the transaction occurring between the user terminals in the cryptocurrency exchange server in the account of the user terminal.

In contrast, when a user terminal withdraws his _{cryptocurrency} to another wallet (t _o21 ), a transaction actually occurs in the _{cryptocurrency} network and is recorded in the blockchain.

However, the exchange wallet of the conventional cryptocurrency exchange server has a problem when airdrops the cryptocurrency. Here, the airdrop referred to herein means that the user receives the cryptocurrency free of charge by any means of receiving a fork, a hard spoon or a token for free. Here, the free cryptocurrency means that the user terminal receives a cryptocurrency without performing a specific task or performing any action but without paying a price.

For example, an airdrop can be a fork in the blockchain in Bitcoin, free to receive new cryptocurrencies such as Bitcoin Gold, a free airdrop of tokens, or a hard spoon ( It includes everything from getting a new cryptocurrency free of charge by a hard spoon).

Here, the hard spoon was launched by cosmos coin

It is a non-airdrop method, and tokens are new cryptocurrencies issued on platforms such as Ethereum and EOS. In other words, developers can easily issue and distribute new cryptocurrency tokens using the platform without having to create a new blockchain.

Issuing tokens to create a new cryptocurrency, many developers are issuing a cryptocurrency as a token because it greatly reduces the development time of the cryptocurrency. It often issues new tokens, airdrops tokens indiscriminately, or airdrops certain cryptocurrency wallets.

However, in the conventional cryptocurrency exchange server, since all the cryptocurrencies are stored in the exchange wallet 25, the air wallet of the cryptocurrency is made to the exchange wallet 25. As a result, if the cryptocurrency exchange server distributes the airdropped cryptocurrency to the user terminal, a snapshot that stores the account history of the cryptocurrency of all the user terminals of the cryptocurrency exchange server at the time of receiving the airdrop. Should proceed. However, since the cryptocurrency exchange server cannot monitor all the airdrops in real time and store a snapshot thereof, the cryptocurrency exchange server generally does not distribute the airdropped cryptocurrency to the user terminal.
